ADJUSTABLE BRlDLE-ROD FOR RAILWAY-SWITCHES.

SPECIFICATION forming part of Letters Patent No. 730,932, dated June 16,1903.

Application filed April 21,1903.

To all whom, it may concern.-

Be it known that we, HARRY ALBERTO LAW- LER and JOSEPH PERRY KERR,citizens of the United States, residing at Springfield, in the county ofGreene and State of Missouri, have invented certain new and usefulImprovements in Adjustable Bridle-Rods for Railway-Switches; and we dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

Our invention relates to improvements in adjustable bridle-rods forrailway-switches, the object of which is to provide a cheap, simple,durable, and convenient device for quickly, easily, and permanentlysecuring the points of the switches in the desired position or distanceapart. These objects we accomplish by means of the device illustrated inthe accompanying drawings, forming a part of this specification, inwhich-- Figure l is a view in elevation of the entire Fig. 2 is alongitudinal vertical section of the device. Fig. 3 is a view of thelever or safety-clamp detached.

Similar letters represent corresponding parts in the several figures.

A and B represent the two parts of the bridle-rod. Said parts are eachprovided with notches A and B any desired size, for interlocking orreceiving each other. In the end of each of the said parts A and B is aslot A and B and also have a hole for receiving a bolt. Said slotspermit of an adjustment in length of the rod.

O is a yoke for holding the parts more firmly together andis providedwith a spring-clamp or lever D. One end of said spring-clamp D passes inunder the yoke, and the lower projecting part of the clamp or leverforms a fulcrum D for giving a leverage when the bolt at the other endof the clamp in the hole D is drawn or screwed down,thus holding theparts Serial No. 153,660. (No model.)

firmly together and by the spring tension of the lever prevents the nutfrom working ofi the bolt E, which passes through the open ing D. Byloosening the nuts on the bolts E and F the parts may be loosened andthe rod adjusted in length and the same prevent ed from slipping ormoving by reason of the notches A and B and the clamp tension, as abovespecified.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent of the United States, is

1. An adjustable bridierod for railwayswitches, consisting of two partsdetachably connected by means of bolts resting in slots and teeth ornotches which interlock, substantially as shown and described.

2. An adjustable bridle-rod for railwayswitches, consisting of two partsdetachably connected by means of bolts in slots; said parts providedwith notches, and a yoke provided with a spring-clamp, for firmlysecuring the same together, and to prevent one of 'the nuts fromunscrewing, substantially as shown and described and for the purposespecified.

3; An adjustable bridlerod, for railwayswitches consisting of two partsdetachably connected, said parts having teeth or notches for engagingeach other, also slots for receiving bolts to permit of linealadjustment; and a clamp formed of a yoke and a lever to hold the saidparts together at one point, while the spring end of the lever preventsthe nut from unscrewing and holds them together at the opposite end,substantially as shown and described. g a

In testimony whereof We affix our signatures in presence of twowitnesses.
